To become Christian is to receive a new identity. You no longer allow others to tell you who you are. Christ now claims you and instructs you. A Christian is one who has “put on Christ.”
Baptism celebrates becoming that new person. That is why the church’s ritual begins with putting off the old, renouncing sin and the evil powers of the world, and pledging our loyalty to Christ.
3. Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
4. Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life
5 For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
6 Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
